This study aims to implement and refine research protocols required for a full-scale randomized controlled trial of Psychological First Aid (PFA) for adult victims of crime. PFA is a promising acute intervention designed to reduce the severity and duration of trauma-related distress. Law Enforcement Victim Advocates are being trained to implement PFA with adult crime victims. A pilot trial is comparing PFA to usual victim advocacy services on key psychiatric outcomes from baseline through 4 months post-baseline.
